K2: Support for inter-module interaction for @SubclassOptInRequired

The inter-module interaction was partially supported, but the
DiagnosticCompilerTestFE10TestdataTestGenerated and
LFirPreresolvedReversedDiagnosticCompilerFE10TestDataTestGenerated were
failing. This is because the arguments of annotations were not fully
resolved in loadExperimentalitiesFromAnnotationTo function.
